How to use a JSON formatter
A JSON formatter helps you turn compressed or messy JSON into clean, readable structure so debugging and review are faster.
- Paste your raw JSON into the input field.
- Run format/validate to pretty-print the object with indentation.
- Fix syntax issues if an error appears, then re-run.
- Copy the formatted output for API docs, logs, or code review.
Formatting does not change the meaning of JSON data. It only improves readability by adding line breaks and spacing.
